SAFETY-RAZOR.

Specicatio'n of Letters Patent.

Patented Apr. 9, 1912.

Application filed .Tune 10, .1905. Serial No. 264,603.

Improvements in Safety-Razors, of which the following is aspecification.

My invention relates to improvements in the class of safety razorswherein a frame having a guard is provided with a pivotally supportedblade, and with means for rocking the blade for stropping its edge whilethe blade remains connected with the frame, which class of razors isdisclosed in Letters Patent No. 759,262 issued to me May 10, 1904.

Objects of my invention are as follows to simplify the means forremovably supporting the blade in its holder and to provide a holder'adapted to hold blades of different styles, such as blades having asingle cutting edge and a solid back, and blades having a .plurality ofcutting edges; to simplify the means for rocking the blade; to permitthe guard to be readily adjusted. toward and from the blade edge toconveniently release the blade to permit it to be rocked for stroppingpurposes; to permit adjustment ofthe guard with respect to the bladeedge to allow a more or less close shave to be obtained; and alsogenerally to simplify and improve the construction of such razors.

In carrying out my invention I provide a frame, and a blade holderpivotally supported thereby and having two end members adapted to engagethe ends of a blade, one of said members being movable toward and fromthe other, means for locking said members in rotative engagement, andmeans for rocking the blade holder; I also provide the blade holder witha gear that meshes with a gear on a roller journaled in the framebeneath the holder and provide the fralne with guides for the strop onopposite sides of the roller, whereby the strop Works against the underside of the roller or its side farthest. from the holder for causingthel edge of the blade to swing in the reverse direction to travel ofthe frame.

In carrying out a further part of my vinvention I provide the frame witha guard, and guides for the guard' so that it may readily slide towardand from the blade edge, a finger piece connected with the guard, and aspring for normally holding the guard against the razor edge, wherebywhen said finger is pressed upon it will move the guard away from therazor edge to release the latter for stropping purposes. In 'theconstruction of my improved guard I provide two members, one havingordinary'comb like teeth and the other havingmeans to engage a bladeedge near v,its corners, with means for regulating the distance betweenthe two members of the guard for adjusting the guard teeth more or less`closely to the blade edge.

My invention also comprises the novel details of improvement that willbe more fully hereinafter set forth and then pointed out in Lthe claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

-Figure l is a plan view of a safety razor embodying my invention, Fig.2 is a cross section thereof, enlarged, on the line 2, 2, in Fig. 1,Fig. 3 is a detail perspective view of the guard, Fig. 4 is a similarview of part of the blade holder, Fig. 5 is a side view Of the razorlooking from the under side in Fig. l, Fig. 6 is a View similar to Fig.5, looking from the opposite side, Fig. 7 is a plan view, partly insection, on an enlarged scale, Fig. 8 is a rearview of the razor,showing the manner of adjusting the blade in its holder, and Fig. 9 is adetail view of a blade having cutting edges on oppositeA constructionshown the member 4 is secured,

upon or formed with 'a tube or bearing 6. having one end partly cutaway,as at 6, and secured upon shaft 2, as by a pin 7, and the member 5 issecured to or formed with a tube or bearing. 8 mounted to slide uponshaft 2 and having an end partly cut away, as at 8, to match the'cutaway part 6a of tube 6, whereby said tubes have sliding enjf faces so asto rock in unison by and with shaft 2. Tube 8 is sufficiently short toenable itto slide along shaft 2 between tube G and upright 1b for thelpurpose of receiving and releasing the blade 9, but when the member 5is pressed toward the member 4- v the blade will be firmly held betweensaid members, as by friction between shaft 2 and tube 8 and theinterlocking sections 6, 8a. The blade shown, except in Fig. 9, isgenerally of well known construction having a cutting edge and a solidback portion. In Fig. i9 the blade 9a is indicated as a thin blad s, tobe made' preferably of sheet steel, provided with cutting edges onopposite sid s and having lugs 9b projecting from its en s adapted toenter slots or recesses 10 in the members 4L, 5, of the blade holder,whereby such thin blade 9a may be firmly secured in the holder. Byhaving the projections db disposed centrally of the blade the -lattermay be readily adjusted in its holder to enable either edge to be usedas desired.

The blade holder or its shaft 2 is pro-a vided with a gear 11 thatmeshes with a gear 12 secured to roller 3, a space being providedthrough the frame beneath roller 3 for .the passage of a strop, wherebyas the frame is reciprocated along the strop the engagement of roller 3with the strop will' cause the blade holder to rock for stropping theedge of the blade. At 13, 14 the frame is provided with guides,preferably in the form of rollers journaled in the frame on oppositesides of roller 3 against which the strop may bear, whereby when thestrop is in position between rollers 13 and 14 and held taut and theframe is reciprocated the tension of the strop against roller 3 willcause the blade holder to rock back and forth.

The guard device for the edge of the blade is arranged as followsz-At 15is a plate or bar having its end portions or lugs 15a received freely inslots or guides 16 on the extended members 1c of the main frame, theplate 15 serving as a rest for the blade edge andhaving lips or lugs 15bbent upwardly to receive the blade to hold the latter on the plateorprest. At 15c vis a plate or bar having comb-like teeth 15d to co-actwith the edge of the blade, which plate 15c is carried by plate 15 andmovable with relation thereto, thereby being adjustable toward and fromthe edge of the blade. For this purpose I have shown the plates 15 and15c connected at their rear edges by hinge like or spring members 15.The plates'15 and 15c and the hinge members 15e together with the' lugs15b and teeth 15d may be stamped from a single piece of metal, bent at.the parts 1'5E substantially into the relation shownin Fig. 3, themembers 15 acting in the nature of a spring to hold the plates 15, 15cnormally apart. I provide means for causing the comb-like teeth 15d tobe adjusted toward and from the blade edge, as in a vertical directionwith respect thereto, and for this purpose I have shown a screw 17having threads meshing in a threaded aperture inplate 15c and providedwith a shank 17a journaled in an aperture in plate 15 (see Fig. 2)whereby when the screw 17 is rotated the plates 15 and 15c may beadjusted toward or from each other and held by the tension of themembers 15e in such adjusted positions. plate 15 has a substantiallypermanent positio-n with respect to the blade edge that is engaged bythe lugs 15b the comb-like guard 15d may be adjusted toward or from thevblade edge and firmly held to permit a more or less close shave to beobtained.

The means for adjusting the guard toward and from the blade edge topermit the blade to be released for stropping purposes are as followsz-At 20 is a bar or rod movably connected at one end with the guard andguided at the other end by the handle 21 that is secured to frame 1, aspring 22 acting on rod 20 and handle 21 serving normally to hold thelugs 15b. against the blade edge. At`23 the rod 20 is shown providedwith a finger piece projecting through an aperture in the back of handle21, the spring 22 being shown within handle 21 and bearing againstfinger piece 23. and against the handle see Fig. 2). The spring shownhas a central coil at 22l and eyes 22h, 22c that receive rod 20, eye 22bbearing against iinger piece 23 and eye 22C bearing against the handle.For convenience in manufacture I have shown rod 20 as provided with aneye 20a at its outer end located between the members 15e and receiving apiece 15f, that connectsmembers 15e which may be stamped integral withthe members 15e or may be va separate pin connecting said members withthe eye 20a. 'The arrangement shown permits a relatively loose orpivotal connection between rod 20 and the guard, whereby the guard mayadjust itself to various positions with respect to the blade edge, toenable the lugs 15b to engage the blade edge, notwithstanding unevennessof the latter that may occur.. through wear. With this constructionspring 22 through rod 20 normally tends to draw the guard toward thcblade edge to cause the lugs 15b to hold the blade .firmly with respectto the guard for shaving purposes, but when it is desired to release theblade from the guard for rocking and stropping the blade it is'merelynecessary to press finger piece 23, lwhich by pushing By this means, asthe rod 20 will slide the guard and its lugs 15b away from .the bladeedge, (as shown in Fig; 2), whereby the blade will be free to be raisedl (as in dotted lines in said figure),

to permit a strop to be passed through the frame beneath roller 3, sothat by then holding the strop taut and reciprocating the frame alongthe strop`v the blade will be rocked for stropping its edge. Tore-adjust the blade edge to the guard the latter is pushed outwardly, bypushing against iinger piece Q3, the blade is lowered against the guard,the finger piece'is released, spring 22 acting to draw the guard againstthel blade, and the lugs 15b will engagey the blade, (see Fig. 1.)

The various` details of construction shown and described may be variedand changes made Without departing from the spirit of my invention. j

I do not in this application separately claim the blade holder and themeans for rocking the same, as the same are included in my applicationfor patent on stropping machines filed October 21, 1911.
